ADP3110A Dual Bootstrapped 12 V MOSFET Driver with Output Disable

The ADP3110A is a dual high-voltage MOSFET driver optimized for driving two N-channel MOSFETs, the two switches in a non-isolated synchronous buck power converter. Manufactured by Analog Devices Inc., this driver is capable of effectively controlling power delivery by providing powerful gate drive for the MOSFETs.

With an operating range of 10 V to 20 V, the ADP3110A includes a bootstrapped high-side driver that ensures the high-side N-channel MOSFET is driven properly even at high switch node voltages. This is particularly important for applications that demand high current and efficiency, as it allows for the use of low R_DS(on) MOSFETs.

The ADP3110A features an adaptive non-overlapping drive function that prevents both the high-side and low-side MOSFETs from conducting simultaneously, thus eliminating the risk of shoot-through and increasing system reliability. The device also incorporates an output disable function that provides an additional layer of protection by allowing the immediate shutdown of the MOSFETs driving the outputs when necessary.

Designed with versatility in mind, the ADP3110A is suitable for a wide range of applications, including synchronous rectification for isolated power supplies, motor control, and high-performance DC-to-DC converters. Its robust design includes under-voltage lockout protection and a fast propagation delay of 25 ns, which ensures quick response to control inputs, enhancing the efficiency of the power conversion process.

For ease of integration, the ADP3110A is available in an 8-lead SOIC package. It is specified for operation over the industrial temperature range of -40°C to +125°C, making it a reliable choice for demanding industrial environments. With its combination of features and performance, the ADP3110A from Analog Devices Inc. is an ideal solution for power management applications that require high efficiency, compact design, and robust operation.
